Players have been both excited and worried to find that Zynga might be adding the option to increase the population cap or normal Homes in CityVille. CityVille player and forum contributor mdavidson provided the above image of his game, detailing that all Housing in the game will include potential population upgrades in their tooltips. More specifically, when hovering over a House in the Build menu, a new message will appear that reads, "Up to 350," in the case of this screenshot.

We imagine that the number will be based on the cost and size of each House, though the method for improving this population cap has yet to be seen. This change could provide a solution to the growing problem of space in CityVille, allowing players to increase population without having to place more buildings. Regardless of whether a CityVille forum moderator named forgotn confirmed the change as "part of a feature that is being rolled out gradually," we're going to throw this one into the "Rumor" pile until we get official word from Zynga.
